Title: Pseudo-Dynamic Test Method with Sub-Structure Technique Based on Finite Element Software OpenSees
Abstract: Pseudo-dynamic test method with sub-structure technique has been developed to combine finite element software and electro hydraulic servo system.Test data of electro hydraulic servo system MTS Flextest GT and analysis data of finite element software OpenSees are exchanged successfully by the collaborative system OpenFresco.Then,the seismic response of one bay one story steel frame structure is experimentally studied.The results show that the MTS Flextest GT system can effectively receive and respond the displacement com-mands of OpenSees,and the actuator's aim displacements accord with the actuator's feedback displacements.The communications between MTS Flextest GT and OpenSees are stable.By comparing the test results with OpenSees simulation results,they accorded accurately.It is proved that the collaborative system OpenFresco can research sub-component of structures using pseudo-dynamic test method with sub-structure technique experimentally.The function of pseudo-dynamic test method is widely expanded.
